Question

我在启动Cassandra节点时遇到问题。这是错误：

org.apache.cassandra.db.commitlog.CommitLogReadHandler$CommitLogReadException: Could not read commit log descriptor in file C:\apache-cassandra-3_extracted\apache-cassandra-3.10\data\commitlog\CommitLog-6-1497856002934.log

有谁知道如何开始它？

这是在启动时读取commitlog的问题。您应该检查文件是否为空或具有错误的权限。

如果群集上有多个此节点 - 并且您的复制因子高于1，则只需删除此单个commitlog文件并尝试再次启动cassandra并运行修复。

这也适用于单节点或复制因子1 - 但此日志文件中的upserts数据丢失。

Cassandra节点没有启动;提交日志文件问题？
